As an important anti-corrosion steel pipe, hot-dip plastic-coated steel pipe has attracted much attention for its anti-corrosion performance.1. Manufacturing process: The manufacturing process of hot-dip plastic-coated steel pipes mainly includes surface treatment, preheating, spraying, and curing.
1. A galvanized steel pipe reacts molten metal with the iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel pipe first. To remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an aqueous s
The following methods can slow down or prevent steel pipe corrosion:1. Adjust measures to local conditions: rationally select steel pipe building materials, and select different types of materials according to different transportation media and environmental conditions.2. Steel pipe plus DC power su
Corrosion of clean water pipes:Metal pipes account for 90% of my country's urban water supply pipelines. Whether they are cast iron or carbon steel pipes, corrosion, and scaling will occur during long-term operation. With the increase in service life, the corrosion in metal pipelines becomes more an
ERW (Electric Resistance Welded) steel pipes can be susceptible to corrosion issues, especially in environments with high humidity, exposure to chemicals, or soil conditions that promote corrosion. Some common corrosion problems associated with ERW steel pipes include:1. General Corrosion: Over time
Cold expanded of large diameter straight welded pipe is a use of hydraulic or mechanical means urging the steel pipe from the steel wall along the radially outward dilatation pressure molding process. Mechanical than hydraulic mode, the device is simple and more efficient use of steel in high-precis
Hot-rolled steel is a commonly used material in construction and manufacturing due to its strength and versatility. However, like any material, it has its disadvantages:1. Shape Limitations: Hot-rolled steel sheets and plates typically have a rougher surface texture compared to cold-rolled steel. Th
Advantages of Electric Resistance Welding:1. Fast and efficient: Electric resistance welding is a fast and efficient method of welding two or more metal parts together. It typically involves placing the parts in contact with each other and passing an electric current through them, causing them to me
When it comes to shape requirements for LSAW steel pipes, several factors need to be considered to ensure the proper functionality and performance of the pipe in the field:1. Dimensional Accuracy: LSAW pipes must meet precise dimensional specifications, including diameter, wall thickness, and length
Annealing is to heat the cold-rolled precision bright steel pipe to an appropriate temperature, adopt different holding times according to the material and workpiece size, and then slowly cool it. The purpose is to make the internal structure of the metal reach or approach an equilibrium state and o
